If you are just talking about Jack Straw - then Jerry solos in E mixolydian. He uses the mixolydian mode the most - then major (ionian) and then dorian.

That's the meat & potatoes of Jerry's leads - of course all of the spices and flavorings are when he mixes modes & throws in the other ones - or diminished scales... But 85% of it all is the the first 3 that I mentioned.

Its cool. Thanks of for the advice I'l look into using the mixo during this song. It does appear that jerry uses the mixolydian scales alot as I have seen it in many of their songs- china cat, dark star, althea ect. Thanks for the help again in identifying the scales.

E mixolydian--------E-F#-Ab-A-B-C#-D-E over the E chordA Ionian--------------------A-B-C#-D-E-F#-Ab-A over the A chordD Lydian---------------------------D-E-F#-Ab-A-B-C#-D over the D & Bm chords

I don't want to complicate things but depending on where your head is this may help as well. As far as playing modes for this you can think as outlined above. These 3 modes, you'll notice, are all the same notes. It may help to think of these distinctions while soloing over the specific chords along with focusing on the blue colored notes as well. They are the triad notes that form the structure of the chord. I added the B note in D Lydian for the Bm chord. It'll help have the solo 'fit' and resonate within the chords. The most literal expression of this would be playing arpeggios or simply picking out the chords on your way through the progression. Beginning and ending phrasing on these colored notes while playing over the respective chords will give coherence

You can just think E mixo and keep the chord triads in mind while soloing if the whole mode thing seems confusing.

Anyway, sorry for the hijack. Back to the excellent advice, which I am glad to say actually put musical terminology to the shit I've been piecing together by ear for lo these many years, but couldn't quite figure out why it may actually work (on the rare occasion it actually does). Love learning stuff here...
